Abstract

Despite the importance of Type la supernovae as standard candles for cosmology and to the chemical evolution of the Universe, we still have no consistent picture of the nature of these events. Much progress has been made in the hydrodynamical explosion modelling of supernovae la in the last few years and fully 3-D explosion models are now available. However those simulations are not directly comparable to observations: to constrain explosion models, radiative transfer calculations must be carried out We present a new 3-D Monte Carlo radiative transfer code which allows forward modelling of the spectral evolution of Type la supernovae from first principles, using hydrodynamical explosion models as input Here, as a first application, we calculate line-of-sight dependent colour light curves for a toy model of an off-centre explosion.
